HYDROCARBON-VAPOR GENERATOR AND BURNER.-

SPECIFICATION forming part of Letters Patent No. 275,124, dated April 3, 1883.

' Application filed January 6, 1883. (No model.)

To all whom it may concern:

Be it known that we, ISRAEL R..BLUMEN- BERG and HENRY W. WHITING, citizens of the United States of America, residing respectively at \Vashington, District of Columbia, and Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hydrocarbon-Vapor Generators and Burners and Flame-Expanders, of which the followingis aspecification,reference being had therein to the accompanying drawings.

Our invention relates to improvements in hydrocarbon burners for furnaces and other :5 mechanical purposes; and it consists in constructing within the bulbous base of a burner a globulous chamber connected by a small orifice with an adjoining compartment, and in so constructing and arranging the chambers and Y the induction-pipes that the jets of steam and oil used in forming the vapor when injected therein, while tending to create a vacuum atthe periphery of the globulous chamber, will form double eddying currents, and thereby become thoroughly mingled before being ejected through the burner-tip.

It also consists in a diaphragm having a con. tracted orifice located in the vapor-generating chamber, in combination with contracted ori- 3o fice connecting the globulous receiving and cylindrical mingling chambers, to facilitate the mingling of the vapor and concentrate the force of the vapor-currents and cause them to flow with greater head as they pass through 5 and from the burner-tip, whereby more complete combustion is obtained, all of which will be more particularly pointed out hereinafter.

Similar letters of reference indicate corresponding parts. I

a is the bulbous base of an articulated burner, B, within which is a globulous chamber, a,.having a small outlet, a connecting with the compartment b. Into the globulous chamber a are introduced and secured the nozzle ends of the steam and oil induction pipes d and 6, respectively, and, when required, an airblast pipe, 0.

his a removable diaphragm having a passage-way therein for the vapor.

d, e, and 0 are metal pipes secured by one end, respectively, in the burner. These pipes serve as steam and oil induction pipes or conduits and an air-blast pipe.

f is a suitable stop-cock.

B is the complete articulated burner ready for use.

The diameter of the chamber a is greater than the diameter of the body I), to which it is secured and forms the base; and the orifice a by which the chamber a and compartment 1) communicate, is preferably less in diameter than the compartment 1). The chamber a is giobulous in form, and so constructed, and the induction steam and oil pipes are so arranged, that thejets of steam and oil employed in forming the'vapor will, while tending to create a vacuum at the periphery of the chamber a, form double eddying currents of vapor while passing through and from one chamber into the other, whereby the oil will be thoroughly vaporized and the two completely mingled before reaching the burner. This end will be more fully realized when the removable dia.- phragm h, with its outleth, smallerin diameter than the orifice a has been introduced into the throat of the burner between the burner-tip c and the minglingcompartment I). Into the base a, entering the chamber a, are introduced and secured the nozzle ends of one or more steam-pipes, d, and one or more oil-induction pipes, 0, one, two, three, or more each, as experience may suggesttor the power demand, and, when required, an air-blast pipe, 0. These pipes are connected by the opposite ends to a steam-boiler, an oil-tank, and a blast, respectively, and each is provided with a suitable stop-cocl ,f, for governing the flow.

The mingling-compartment b is a plain cylinder, preferably smaller at the upper than at the lower end; or, if desired, it may be slightly bulbous. This tube or cylinder 1) is the body of the burner, and is secured by a screw or otherwise onto the bulbous base a, and receives on its smaller end the burner-tip c, and is provided with a screw or shoulder for securing the diaphragm h in place. The steam and oil vapor, passing from the globulous chamber a by the orifice a enters this compartment in a series of currents, which, when set back upon themselves, by coming in contact with the diaphragm h, intermingle with each other and become thoroughly mingled in ummz.

The metal diaphragm h has a passage, h,

through which the vapor passes from the mingling-chamber to the burner-tip, and is so constructed that when it is desired to use it, either to cause the vapor to the more thoroughly mingle or to concentrate the force and give greater head to the flow of vapor, it may be inserted and secured in the throat of the burner by a screw or any approved method. The passage it, though it may be of any form of construction, is preferably funnel-shaped, growing smaller toward the burner-tip, and will best serve the purpose by terminating in a nozzle.

It will be observed that the burner is to be used in furnaces and under boilers varying considerably in length, that a burner which throws a flame but ten feet would be useless under a boiler thirty to forty feet in length. By inserting the diaphragm h and modifying the form of the passage h, this embarassment is in a great measure overcome, and then by introducing the air-blast pipe 0 the flame can be wholly controlled and the end sought be accomplished.

The burner-tip cis a plain thimble-shaped cap, which is secured onto the upper or smaller end'of the cylindrical shell I) by a screw or any other suitable device, and it is perforated in the end, as shown by c, c, 0 and c Fig.8, for the passage ofthe vapor, and has a bolt-hole for the bolt t employed in securing-thereon the flame-expander. As the flame of the burner is generated at the tip of the burner, it is preferably made of material that will best withstand the action of the flame, the perforations it being so arranged as to throw the jets of vapor in the direction of the lateral limits of the flame-expander.

The flame-expander It has an irregularly inverted coneshape body, at, provided with spirally-adjusted wings in thereon. This expander works upon ajournal-bolt, i, by which it is held in plaee at the tip of the burner-tip c, and is by the flow of the vapor and rush of the flames so revolved onits axis that it gives an agitated rolling motion to the flame. The flame-expanders is, W, k", and k having no wings, do not revolve, but'simply spread the flame out under the crown-sheet of the boiler or to the full width of the furnace.

The steam-induction pipes 01 d are ordinary metal pipes with a valve, f, by which the quantity of steam admitted to the chamber a can be regulated. These pipes are introduced into and secured in the base of the burner. The oil-induction pipes e c. are also small metal pipes provided with valves f, by which the oil flow is regulated. The end of these pipes are also introduced and secured in the base of the burner.

The pipe 0 is an ordinary small metal pipe provided with a stop-cock connecting with an air-blast, one end to be secured in the base of the burner when used. The interior or end of these pipes within the burner is made small for two purposes: first, that they'may not admit too large a quantity into the burner at the one time, and, second, to prevent the vapor from forcing itself backward into the pipes.

Having nowfully described our invention, what we claim as novel, and desire to secure by Letters Patent, is-
